Magnasphere MSS-301C 1" Recessed/Concealed Multi-Switch Contact with Switch, Closed Loop, Black

Secure doors and windows without sacrificing aesthetics — the Magnasphere MSS-301C magnetic contact delivers reliable, tamper‑resistant protection for commercial and residential security systems. As a recessed/concealed magnetic contact, the MSS-301C installs flush into frames with a compact 1" diameter, making it ideal for surveillance, intrusion detection, and continuous monitoring where discretion matters. Built with Magnasphere's patented switch technology, this closed-loop (N.C.) contact resists permanent contact welding from surges or deliberate defeat attempts, keeping alarm circuits dependable under stress. The unit ships with wire leads and an armored option for enhanced durability, and its 0.13" standard gap maintains consistent triggering across repeated use. Compatible with virtually all control panels, the MSS-301C integrates easily into access control, alarm, and remote monitoring setups. TAA-compliant and American-made, it meets procurement standards for institutional installations. Add the Magnasphere MSS-301C to your next security deployment for a low-profile, high-reliability contact — perfect for door/window monitoring, perimeter intrusion, and surveillance system integration.
